SAMUEL DARLIXG, OF BANGOR, MAINE.

Specitication forming part of Letters Patent No. 44,611, dated October l1, 1864.

To all whom it may concern: i Be it known that I, SAMUEL DAELING, a 1 resident of Bangor, in the county ot' Peuobscot and State ot' Maine, have invented an Improved Apparatus for Weighing; and I do i hereby declare the same to be fully described E in the following specification and represented in the accompanying drawings, of whichl Figure 1 is a top view. Figs. 2 and 3 are opposite side elevations; Fig. 4, an under side view. Fig. 5 is a top view, and Fig. G a side elevation, and Fig. 7 a transversesection, of t the two ounce weight, and with the beam ofiv the said weighing apparatus. Figs. S, 9, and 10 are similar views of the one-pound weight i ot' such apparatus. Fig. 1l is a crosssection of the scale-beam. i

This weighing apparatus consists of a scale- 5 beam A2 asiidin 'wei lit B2 anda bod or its equivalent' for supporting an article to be weighed, the nature of my invention or imp provenients being' found in the construction of the said beam and the weight, and in the arrangement of a series of scales or divisions, and a series of fnlcra, the whole being hereinafter described. The scale-beam may be about twelve inches in length, and ot' the 5 sectional form as exhibited in Fig. l1, in which i is shown a thin bar, a, provided with two ilanges, b c, extending from it. The whole. may be made of sheet metal, bent into the requisite form, and for such purpose tinned sheet-iron may be employed to good advantage, as it will be of sufficient strength, and

as the part for sustaining the hod being fixed in their places, in part, by the aid ot' solder i applied to them and the beam. lhe beam is i to be divided along the upper part of each", side oi' it into divisional parts of one-sixteenth i ot' aan inch each, this being marked and numi bered, as shown in Figs. 2 and 3. Furtherl more, the beam is provided with four fulcra or pivots, (marked A B C D in Figs. 2, 3, and 4,) each ot' such fulcra being a, steel bar, eX- tended across and projectin g below the bottom surface of the beam, and having its loweri edge beveled, as shown in the gures. One

' side of the beam may be marked 02., and

the other side Lbs.,7 the smaller or twoounce weight being applicable to the scales g on one sido, or that marked 02., the larger i f thescales for the diti'erent fulcra.

the side marked Oz.

or pound weight beingfor the scales ot' the other side. Ou cit-her side of the beam are three rows of figures, which are to indicate Those on denote the weight in ounces when the fulcra A B C are used with the two-ounce weightthat is, theupper row is used for the fulcrum the fulcrum B, and the lowest row, or that on the flange, is employed when the fulcrum C is used. The fulcra letters are also stamped in the beam and against the rows ot' tigures, to be used with the di'erent fulcraindicated by such letters. On the opposite side of the beam, or that marked Lbs.,77 the fulcra GL D only are to be used with the pound-weight, the

A, the middle row for iulcrum D being employed when the hod is supported from the notch S, which requires a separate row of. figures. In ali other cases the hod is to be suspended from the notch X, the said two notches being formed in a saddle-bar, fr, arranged at the lower part of an opening', y, made at one end of the beam in manner as shown in the drawings. The uppermost row of figures on the last-mentioned side ot' the beam shows the weights in pounds when the fulcrum C is used for supporting the beam. The middle row of figures on such side represents the weights in pounds when the fulcrum D is used, and finally the lowest row of tigures, or that on the iiange ot' such side, shows the weights in Vpounds when the fulcrum D is used and the hod is suspended from the notch S. When either of the beam-weightsis used,

its arm orrprojection should be arranged so as to be between the saddle-'bar and the rest of the weight. Each of the said weights is constructed with a groove, a, formed across it to enable the weight to straddle and be slid on the upper part of Ithe beam. The said weight also hasan index-arm, b, extending from it, and so as to project over the upper edge of the beam and have the index-face c ot' the arm in the same plane with the side of the beam on which are the divisions for the indices of the said arm. The vertical index-face ot' the arm is to be marked with three indices or vertical lines, one for eachfulcrumwith which the weight is intended to be used, the mark for eachi'ulcrum being denoted by a letter corresponding to that of the said fulcrum. When the mark stamped A on the arm ot' the two ounce weight is directly over the longerI mark, stamped o on the bezun, the soule-that is, the hod and beamwill balance ou the full arrange uttour inches from the notch X. The fuleruin B is two inches from such note-h, the fulorum C being one inch, and the inlcrum l) being one-half :in inch from the said notch.

The advantages of this scale nre to be found in its portability and itsV chenpness ot' construction, as verylight. as well as much heavier bodies muy be-\\'eighed by it with great nceuraey.
